From: Daily rhythms in food intake and locomotor activity in a colony of domestic cats
Mean daily covered distance (metres, top) and food consumption (grammes, bottom) of the cats (n = 14) every hour. Box plots represent first (Q1), second (median) and third quartile (Q3), minimum, and maximum of the data, as well as the smallest data superior to the low frontier (LF = Q1−1,5 × (Q3 − Q1)) and the highest data inferior to the high frontier (HF = Q3 + 1,5*(Q3 − Q1)). (p) indicates a significant peak, (t) indicates a significant trough
